Ok here is my problem,
Code:

ButtonADD:
Gui,Submit,Nohide
FileAppend ,
(
                                            ;<<<<<<< here
::%AbAddName%::%FullAddName%
), AbbreviationData.ahk
MsgBox, The abbreviation entered has been added to the library.
Reload
Return

I need that return( enter pressed ) to make sure that each is saved on a new line, although this leaves a lin blank at the top of the text file, how can I eliminate this empty line ?

Edit: I did post this earlier although it seems to have disappeared from existance

What you had asked for:

Code:
ButtonADD:
Gui,Submit,Nohide
FileAppend, % (FileExist("AbbreviationData.ahk") ? "`n" : "" )
            . "::" AbAddName "::" FullAddName, AbbreviationData.ahk
MsgBox, The abbreviation entered has been added to the library.
Reload
Return


But this is simpler:

Code:
ButtonADD:
Gui,Submit,Nohide
FileAppend, % "::" AbAddName "::" FullAddName "`n", AbbreviationData.ahk
MsgBox, The abbreviation entered has been added to the library.
Reload
Return

`n is newline ( or linefeed ) Character that helps by folding long sentences

The following two produce identical results
Code:
MsgBox, % "UserName: " A_UserName "`nComputer: " A_ComputerName
MsgBox, UserName: %A_UserName%`nComputer: %A_ComputerName%
